Red Bull: Felix Baumgartner and other extreme ways to sell an energy drink

'Red Bull' Wing Walk. Paul Steiner, of the Red Bull sky dive team,
teamed up with the Blanix glider team to perform this high-adrenaline stunt.
He climbed out of the cockpit of one glider, walked along the wing and then
front rolled onto a second glider that was travelling underneath it. He then
moved onto the main fuselage of the second glider, while the first glider
turned upside down and flew overhead. This allowed Steiner to reach up and
grab the tail fin, forming a link between the two aircrafts. A testament
both to the sky diver's cool headedness and the skill of the pilots.
